STRIP 0R PIECE FOR BUILDING TOY GIRDERS, BRIDGES, 8w.

SPECIFICATION forming part of Letters Patent No. 413,651, dated October 29, 1889.

Application filed time 28, 1889.

To all whom it may concern.-

Be it known that I, RUSSELL DUANE, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Strips or Pieces for Building Toy Girders, Bridges, &c., of-which the following is a specification, reference being had to the accompanying drawings, forming part hereof, and in which Figure l is a perspective view of a trestlebridge composed of a series of strips or pieces of different con figurations, forming the trusses thereof, suitably pinned to each other and tenoned together, and as so arranged and combined embodying the principal characteristic features of my invention. Figs. 2 and 3 are respectively front elevations, on a larger scale, of the strips or pieces which form the tie pieces pinned to the upper and lower chords constituting the trusses of the bridge. Fig. 4 is a similar' view of one of the tenoned spanning-pieces. Fig. 5 is a similar view of the cross-ties tenoned to the lower longitudinal chords of the trusses, and Fig. 6 is a similar view of one of the recessed fioor strips or pieces of the bridge.

The principal object of my invention is to provide strips or pieces so constructed as that when combined a girder or bridge may be readily formed, and the said invention designed not only to afford amusement to the young, but more particularly to enable them to become instructed to a greater or less eX- tent in the art of building girders, bridges, &c., by their becoming familiarized with the names of the various parts, as well as with their functions as performed in such structure or superstructures.

My invention consists of the parts or pieces constructed, arranged, and combined substantially in the manner hereinafter described, and specifically pointed out in the claims.

Referring to the accompanying drawings for a further description of my invention, A and A are two trusses composed of the upper and lower chords a anda, made up of two series of detachable strips or pieces a anda pinned at a and a to each other, and struts b and b, constructed, preferably, of the same $erial No. 315,900. (No model.)

The object of forming the recesses in the extremities of the floor-strips cl is to enable them to be readily fitted to the ties O with one portion of the end of each strip or piece resting snugly up against the side of the tie O and with the projecting portion thereof restihg on the upper edge of each tie.

' G represents one of the transverse spanning strips or pieces withslots g and g cut therein, as shown in Fig. 4. These transverse spanning strips or pieces G are fitted onto the respective chords a, struts b and b, and diagonally-disposed tie-pieces a, as shown in Fig. 1, and are intended to prevent undue sidewise movement of the structure.

It will be seen that by removing the transverse lower truss-chord ties C and upper truss-chord spanning-pieces G one of the trusses may be used advantageously as a girder for toy-house building and other similar purposes.

It will be obvious that as to minor details slight modifications may be made without departing from the spirit of the invention, and hence I reserve to myself the right to modify the same in the more extended practice thereof.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure'by Letters Patent, is

1. The herein-describedtoy, consisting of the longitudinal strips, the vertical struts, the tie-pieces diagonally disposed and said strips or pieces pinned to each other, the slottedspanning-strips, and the transverse tiepieces, all arranged substantially as shown, and for the purposes set forth.

2. The herein-described toy, consisting of In witness whereof I have hereunto set my the longitudinal truss-chord strips or pieces, signature in the presence of two subscribing 1o struts, and diagonally -disp0sed tie-pieces Witnesses. pinned to each other, the slotted spanning- 5 strips, the slotted transverse tie-pieces, and

the recessed floor-strips, all arranged sub- Vitnesses: stantially as shown, and for the purposes set THOMAS M. SMITH, forth. HERMANN BORMANN.

RUSSELL DUANE.
